R3 is a free, browser-based platform for building interactive 3D on the web: scenes, physics, sound and music, all in your browser.

  • Drop a .blend file and see it in 3D in seconds: no Blender install, no account. https://blender.r3js.org
  • Build with code or with your AI agent: connect Claude, Claude Code, Cursor or VS Code to R3 with "Sign in with R3". https://r3js.org/documentation/mcp
  • Share anything you make as a link anyone can open.

  Short, practical clips: Blender to browser, physics, sound, and building with AI agents.
